I planned to invest in this. But I am not able to do so, because I just have a 5.1.1 Android phone.
I think you can register via tokenmarket.net
AFAIK I can not buy tokens via tokenmarket. They just "advertise" this ICO.
Or am I wrong?
İ dont think that you can buy with tokenamarket.
Nope, you have to be registered through the app to participate. They do this because you are only allowed a single purchase per person during the ICO.
I have tried to download app on my android phone Samsung S3 Neo and it told me my device is incompatible.
A BAD beginning
I believe its because you are running a fairly old device.
